Compression only Springs
Compression only Springs
(OP)
I am trying to translate a long hand matrix analysis for a small portal frame , 2 columns , one beam across, into an excel/VBA. how could I model/include compression only spring for one of the column bases. that is if there is an upward load the spring wont be effective.

You could set the springs as new members with a non-linear material with a normal young modulus in compression and a very small one for tension to avoid convergence problems.
